Grey’s Anatomy: Scoop on the birth of Meredith and Derek’s baby and more on the season 9 finale (Episode 9×24 “Perfect Storm”) from TVLine’s Matt Webb Mitovich

As we enter this final stretch — the Season 9 finale airs next Thursday — here are a few teasers and/or merely interesting anecdotes. For one, you know how Shonda Rhimes famously tweeted that she scrapped her original finale plan for one that gives us a “superstorm”? Well, she says that a bit of bad weather was always coming Seattle’s way, “But it definitely wasn’t going to play out the way that it does now.” Then there was her tweet about having to whisper something to a director during the filming of a finale scene. Rhimes tells us that the top-secret exchange involved a bit of dialogue that was kept out of the script pages, yet was coming up in the scene. (“I just walked down to the set, told the director what we were going to do, and then he did it.”) On a related note — or not — I have this vittle for TVLine reader Jessica, who’s wildly curious about what the finale has in store for Meredith, Derek and the birth of their baby. “It is probably the exact opposite of any situation that anybody would want to go into labor in,” Rhimes says, “but it’s also works exactly how we want it to.” The show boss describes the storyline as “fairly intense,” adding that Ellen Pompeo “did beautiful work.”
